Just in time for the beginning of holiday wish-list writing, along comes BMW with two very tempting disruptions: the next generation of M-tuned sport-utility vehicles, the X5 M and X6 M.

The X5 and X6 are fresh off a redesign—the X6 even fresher than the X5—and the M models join a recently refreshed lineup of gas- and diesel-powered X5 and X6 models. The X5 M and X6 M feature sharper, lower styling cues that remain true to the less powerful models', inside and out. Count us as fans of the striking 21-inch alloy wheels.

The big news is the duo's massive power output: 567 horsepower from a twin-turbocharged V-8 engine, routed to all four wheels through an 8-speed automatic transmission—no dual-clutch transmission here. That's an increase of 20 horsepower over the M models that they replace, and a shocking amount of horsepower regardless. The X5 M and X6 M may be capable of track days, but owners will likely use them to accomplish tasks more mundane. Brakes are ventilated and cross-drilled, and adjustable dampers return in three settings. We're eager to see whether this new generation of M sport-utes will be as capable in corners as it is in a straight line.

Like their predecessors, the X5 M and X6 M will be assembled alongside their less powerful SUV counterparts at BMW's production facility in Spartanburg, S.C.
